DEWALT
A 20V tool-battery hand vacuum with HEPA filtration, six accessories and an LED light. The battery and charger are not included.
People who already own DEWALT 20V batteries and want stronger suction for sand and pet hair.
Anyone starting from zero: add the cost of a battery and charger before you compare it with an all-in-one hand vacuum. It is also dry-only.
In the same 14-vacuum test, the DEWALT measured about 1,295 pascals of suction and 73 CFM, roughly double the suction of the Dustbuster, and was among the easiest to use with good crevice tools. The tester used a third-party battery with an adapter; the Amazon listing is for the tool only.

A 14-vacuum measurement test shows how suction in pascals, airflow in CFM and real pick-up relate. Read the chart, then decide between a hand vacuum, a tool-battery vacuum and a shop vac.

Use a published measurement test to show how far a headline suction number can be from the pressure a tester actually recorded, with a fair-play caveat and two vacuums compared.
